Orientation of Artwork for HEDS-9040 Option T00 (2000 CPR, 23.36mm Rop) and HEDS-9140 Option B00
(1000CPR, 11.00mm Rop)
*Please note that the image side of the codewheel must always be facing the module Side A.
The Index area on the HEDS- 9040 Option T00, 2000 CPR
and HEDS-9140 Option B00, 1000 CPR Encoder Module
has a nonsymmetrical pattern as does the mating Code-
wheel. In order for the Index to operate, the “Rightread-
ing” side of the Codewheel disk (the “Artwork Side”) must
point toward “Side A” of the Module (the side with the
connecting pins).
Because the Encoder Module may be used with either
“Side A” or with “Side B” toward the
Mounting Surface, Avago supplies two versions of Film
Codewheels for use with the Option T00 3-channel
Module and Option B00 3-Channel Module: Codewheel
HEDM-6140 Option TXX and HEDM-5040 Option Bxx has
the Artwork Side on the “Hub Side” of the Codewheel/
hub assembly and works with “Side B” of the Module on
the user’s mounting surface. Codewheel HEDM-6141
Option TXX and HEDM-5041-Bxx has the Artwork Side
opposite the “Hub Side” and works with “Side A” of the
Module on the mounting surface. For the Index to oper-
ate, these parts must be oriented as shown in Figure 7a
and 7b.
* USE HEDM-6141#Txx or HEDM-5041#Bxx
Figure 7a.
